a new and useful Improvement in Tractors,

of whichfthefollowing is a specification.

This invention relates to improvements in tractors, and more particularly relates to the mechanism whereby power derived from the prime mover ofthe tractor may be utilized for driving machinery other than the tractor itself.

Among the objects of this invention are mplicity of construction and greater effectiveness in use.

It has been customary in the construction of' self propelled vehicles to project the crank shaft of the internal combustion engine to a point near either end of the vehicle frame and to apply a drunk to the exinvention has to do more particularly although not exclusively to uses where the engineis placed at a distance from the end of the body frame, making it necessary to extend the crank shaft a long distance. This long extension of thecrank shaft is objectionable because it occupies desirable space in the frame and also requires steadying means to prevent it from vibrating.

Our invention overcomes this objection by combining into asingle structure, means for cranking the engine from one side of the frame and also for transmitting power from the engine for driving external machinery.

T 0 these ends our invention comprises the features of construction and combination of parts hereinafter described and claimed.

In the drawing, Figure 1 is a plan ofa detail partly in section of our invention; Fig. 2 is an end view partly in section of part of the structure illustrated in Fig. 1.

In the drawing, A indicates a portion of the frame or body of a self propelled vehicle upon which is mounted an internal combustion engine B 0.1 usual type having the usual crank shaft 2 projecting from its casing. This crank shaft has secured to it adjoining said casing a bevel gear 3, the teeth of which mesh with another bevel gear 4 which is mounted on the counter shaft 5. This counter shaft is journaled in the hearing 6, which is secured to the frame of the This vehicle and has extensions and 8 secured to the casing of the engine for supporting the shaft 5 with the teeth of the bevel gear 4 evenly meshing with the teeth of the gear 3. The outer end of the counter shaftb projects from one side of the vehicle and parries thereon a loosely journaled drive pulusual construction, so that the pulley can be thrown into and out of revoluble connection with the shaft 5. Formed on the outer end of the shaft 5 is a square head 11, to which a crank handle can be fitted for turning the shaft 9 and imparting revolving motion to the crank shaft 2 of the engine for starting purposes.

T he construction described provides a simple and effective connection for operating external machinery by the engine on the tractor at one side of the frame or body and also provides efi'ective means for cranking the engine from one side of the body.

In accordance with the patent statutes, we have described the principles of opera tion of our invention, together with the apparatus which we now consider to represent the best embodiment thereof, but we desire to have it understood that the construction shown is only illustrative, and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.

Having described our invention what claim as new and desire to protect by Letters Patent is:

1. A tractor having a frame, an engine mounted upon said frame having a longitudinally projecting crank shaft, 1 bevel gear carried by said crank shaft, a counter shaft journaled upon said frame and (5X- tending laterally from one side of said frame and having a bevei gear meshing with the bevel gear on said crank shaft, a drive pui ley loosely dis 'soscd upon said counter shaft, a clutch carried ioy said counter shaft for revolubly connecting said pulley with said shaft, the outer end of said counter shaft being provided with means for engaging with a crank for turning said counter shaft and iinparting revolution to said crank shaft.

2. A tractor, comprising, in combination, a

frame, an engine having its casing mounted This drive pulley is connected torevolve with the shaft 5 by the clutch 10 of iti upon said frame and having a crank shaft projecting from its casing longitudinally of said frame, a counter shaft disposed laterally to said crank shaft and projecting from one side of said frame a journal for said counter shaft mounted upon said frame and engine casing, connecting means between said crank and counter shafts for transmitting motion from said crank shaft to said counter shaft 1;) and vice versa and a pulley carried by said counter shaft for driving external Inacliinery the end of said counter shaft adjoining said pulley being provided with means for engaging with a crank for turning said counter shaft and imparting revoluble motion to said crank shaft.

In testimony whereof, we have signed our names to this specification.
